Researchers at the University of Massachusetts
Reduce mortality by up to 70%
The effect is similar to walking 10,000 steps
One study found that if middle-aged people walked more than 7,000 steps a day, they could reduce the chance of “premature death” (death before average life expectancy by age) by up to 70%. However, the risk of premature death was similar for those who walked more than 10,000 steps and those who walked 7,000 steps.
According to the medical community on the 22nd, researchers at the University of Massachusetts in the United States published the results of the research containing these details in the latest issue of the international scientific journal “JAMA Network Open.” The researchers used data from a large-scale cohort study (CARDIA (Coronary Artery Risk Development in Young Adults)) that has been conducted since 1985. CARDIA is a study that tracks 5,000 young adults among 18 and 30 years to analyze the causes of cardiovascular diseases that develop in old age. The National Institutes of Health (NIH) that conducted this study analyzed the health status of 2,100 participants between the ages of 38 and 50 between 2005 and 2006 who wore a pedometer for 11 years.
The researchers divided the subjects into three groups: a short walk group (less than 7,000 steps), an intermediate group (7,000 to 9999 steps), and a long walk group (more than 10,000 steps). As a result of follow-up, the average group early mortality rate was 50 to 70% lower than the normal early mortality rate. The decrease in early mortality in the walking group was similar to that in the middle group.
In the group with little walking, the mortality rate decreased progressively in proportion to the increase in the number of steps. People who walked 4,000 steps had a 30% lower risk of premature death than those who walked 2,000 steps. This was valid up to 10,000 steps.
The first author of the study, Dr. Amanda Palucci of the University of Massachusetts, said, “If a person walking 4,000 steps walks 5,000 steps, the all-cause mortality rate decreases.
